Vue 3 Mastery: Composition API, Reactivity, and script setupのベスト引用
The big hook here—the thing that changes everything—is that we’re moving away from organizing code by what it is, like 'this is a method' or 'this is a computed property,' and moving toward organizing it by what it does.

The primary shift involves how code is organized within a component. While the Options API separates code by what it is—such as data, methods, and computed properties—the Composition API allows developers to organize code by what it does. This approach prevents logic from being scattered across different sections, making it easier to manage complex features like search logic in a single, cohesive block rather than across five different sections.
Using script setup provides a more streamlined way to work with the Composition API. Unlike the older Options API where execution was fragmented, code within script setup runs every time a component instance is created. This shift offers developers more freedom and 'oxygen' in their workflow, moving away from the 'massive tower of options' and hidden mixins that often made older Vue components difficult to read and maintain over time.
Yes, the Composition API is designed to enhance readability by keeping related logic together. In the traditional Options API, developers often felt like they were baking a cake with ingredients scattered in different rooms. By grouping functionality into logical blocks, the Composition API avoids the frustration of jumping between distant sections of a file. However, it requires discipline to ensure that script setup files remain organized and do not become cluttered like a junk drawer.
